I'm really interested in menstrual cups, mainly because pads are so annoying, and far from eco-friendly. After reading through here and other reviews/groups everywhere, I'm more confused than ever! So, background. I'm 14, a virgin, and have a pretty light flow. I really like the design of the MeLuna Soft (and glitter! I'm a sucker for glitter) but I can't figure out which size to get. While on my period, I can reach my cervix relatively easy with my middle finger (so about three inches), but I dunno if that means I'm a small/medium/whatever. I'd really like to get the right one on the first try...
